Paper Abstract

A novel technique for dispersion compensation is presented. Based on the theoretical analysis, an ideal instance of characteristics of linear chirped fiber Bragg grating (CFBG) with 11 thermal heads and a laboratory instance of characteristics of the CFBG with 5 thermal heads varies with different temperature is shown. They are analyzed at room temperature with variation of the decrease from 3°C to -3°C and the increase from -2°C to 2°C. According to the results of the simulations based on theoretical analysis, the change of micro-heaters temperature will induce the change of grating temperature, and then change the Bragg wavelength, delay and delay slope of the CFBG. Further more, a material experiment is presented. These results show that if the temperature controller is good enough, we will be able to limit the temperature from 0°C to 4°C and we will receive some random dispersion values from -2608.2ps/nm to - 2835.6ps/nm. Therefore, this dispersion compensator can compensate the survival dispersion completely and can be applied to the long-distance transmission and the optical communication system.
